If you are searching for the number that makes the whole expression a perfect square, you need to take b, divide it by 2, then square it, like this:
In this case, b is -7. You would then divide it by 2 to get 3.5, then square it.
You can plug this into a calculator to get an exact value, but this is what c is supposed to be to make a perfect square trinomial. 'b' is always the number next to 'X'.

The answer is C. <3 ans <11
A unit fraction is a fraction whose numerator is 1.
Now we are given the fraction 7/8 here.
So if we have a fraction 1/8, that will be unit fraction.
Now if we multiply it with 7 then we get 7/8.
Answer : The unit fraction of 7/8 is 1/8.
The angle with a measure of 79 degrees and angle b are alternate exterior angles.
Alternate exterior angles from parallel lines are always congruent; thus, the measure of angle b must be 79 degrees as well.
Hope this helps!
